TO WHOM THESE PRESENTS SHALL COME;

Be it known that I, ELISHA W. \VALTON, of the town of Drytown, county of Amedo'r, State of California, have invented a new and useful invention, thaitI call a. Charging and Tamping-Mechine for Splitting Wood,

for which I wish to secure L tters Patent, and of which the following, together with the accompanying dram The purposes ofimy invention are, to cone truot a. machine thntwill contain a ohargeoi. powder of suflicicnt amount to produce a. blast and shutter timber or logs of any size. The barrel that contains the charge also answers the purposes of-a tamper, by the space above the charge-cavity A being solid, except a small cavity, H,

to form the connection between the charge and the cap-nipple. On the outside of the lower end c i'-=the barrel, is v a screw, B, that screws the barrel into an auger-hole bored intothc log nnd eil'ectiiiiliy'closcs the hole. The top end of the barrel is fastened. into a cross-piece, .0, turned up at the ends to form handles I) D; To thia oross'pioce is attached the hammer E, thhtstrikes the cap upon the nipple F, that is'scre'n'ed into the barrel on the uppeiend. The hammer E is operated upon by the spring G, or is made of sufficient weight that it can be operated by a cord passing through the end of the hammer, and n sufliciently hard blow struck to explode the cop upon the nipple to set oil" the charge. I I

The manner of operating the charge and tamping-machine, is to bore o. hole Wlthllll auger, about two ,or three inches deeper than the depth the charge is placed. The machine is then screwed firmly into the cavity, and compresses the air into the sp n co below the charge, in which the powder is exploded, perfectly effecting the objects desired'with it smaller amount of powder than would accomplish the object by any other process.

The hammer that sets off the charge is acted upon by a cord, operated by the parties who may be at a. safe distonce from the charge. The auger-hole is cleaned oi'nny surplus chips by the scrcw-cleaner'K, time leaving a.

clenn cavity for the compressed nir.
